Expression profile and polymorphisms of actin genes in protoscoleces of Echinococcus granulosus from sheep in central Turkey.

The expression levels and polymorphisms of two actin genes, EgactI and EgactII, were investigated in the protoscoleces of Echinococcus granulosus isolated from sheep in the central region of Turkey. Only the EgactII gene was found to be expressed at detectable levels by protoscoleces in the present study. PCR-RFLP analysis and following sequence analysis revealed that a partial EgactI gene is more polymorphic than a partial EgactII gene.
